Windows seems to send two separate calls to NVMe controller configuration. The
first sends configuration info and the second the enable bit. I couldn't
enable the Windows 8.1 in-box NVMe driver with base Qemu. I made the
following change to store the configuration data and then handle enable and
NVMe driver works on Windows 8.1.

I am not a Windows expert and I'm not entirely sure this is the correct
approach. I'm offering it for anyone who wishes to use NVMe on Windows 8.1
using Qemu.

I have tested this change with Linux and Windows guests with NVMe devices.

First pile of s390x patches for 2.4, including:
- some cleanup patches
- sort most of the s390x devices into categories
- support for the new STSI post handler, used to insert vm name and
  friends
- support for the new MEM_OP ioctl (including access register mode)
  for accessing guest memory

The block I/O path includes the asynchronous I/O machinery and
read/write/flush/discard processing.  It somewhat arbitrarily also
includes block migration, which I've found myself reviewing patches for
over the years.
